There's another issue with these thrusters which opens a MASSIVE can of worms:
They don't push against anything - they've been tested in sealed containers inside of vacuum chambers and there's nothing being thrown off and nothing being pushed against.
That means, if they produce 1 gram of thrust at "rest" (there's no such thing as "stationary" in a universal sense), they also produce the same thrust at any speed...
That's a Problem for physics, because if you make one spin around in a circle, the faster it spins, the more power it generates (same torque, more RPM), so basically it's a backdoor into Free Energy...
Currently does not work in any meaningful way because the thrust they produce is so small that you can't get them to spin fast enough to extract meaningful power (the structure can't handle the centrifugal force). But they do create theoretical free energy which is at least enough to troll the shit out of physicists...
